Elena is not (normal) human
Elena has several oddities related to her. First of all, she somehow managed to get D.U.M.A. out of cargo hold in less than a minute, despite saying herself that it's impossible to open it with bare hands. She also refers to humans apparently excluding herself ("humans' intuition is a mystery to me"), effortlessly lifts Raymond despite him struggling, and conspicuously wasn't given a last name. She very well may be an Artificial Human, a Ridiculously Human Robot, or even some sort of higher being in disguise.- Elena is an android, it says so in the demo.
